SAFETX-LOGK FOR PINS.

Specification of Letters Patent.

- Patented Nov. '17, 1908.

Application filed July 31, 1907. Serial No. 386,453.

To all whom it may concern.

Be it known that 1, VVILL1AM A. OLSEN, a citizen of the United States,-residing at New- York, in the county" of New York and State of NewYork, have invented new and useful Improvements in Safety-Locks forPins, of which the following is a specification;

This invention relates to pins or more par ticularly to safety devicesfor securing pins when once locatedand are adapted to be s'ecured to thepoint of the pin in such a man ner after the pin has been passed throughthe article it .is to secure,- that its accidental retraction is hardlypossible as will be more fully described in. the following specifica 1tion, set forth in the claim and illustrated in the drawings whereit'will be seen that the same reference characters are used todistinguish the same parts"- in the several figures. Y Figure l is aperspective .view of a hat pin'wit-h the improved securing device onitsFlg. 2 1s anenlar ed side vlew of same. Fig, 3 is a sectiona view ofthede- V yice on thepoint ofthe in.

The device] is particn arly adaptable for of such a scarf 1n, hat pin orsuch articles of value whic are. free v quently in danger of slippingout of the ar ticle in which they are located and being lost andconsists ofar bead or head-5 which,

may correspond in size and shape with the head 6 of the pin 7. This head5-has a 11101-- inner 'endof the socket 9 .low shank 8 the interior ofabout the same diameter as the end of the pin and the may correspondformed the pin to slide past-.. the headon the-pin requires some forcebut 0 'ficiently to produce a resilient side,

with the point-of the pm as shown.- One 1 sideIO of the shank s isreduced and fiat eflect. An indentation or depression 11 is in thisportion IQ of the shank' and i pro ects far enough inward to decreasethe diameter or widthof the socket atthat point to a degree lessthan thediameter of the pin so that it forms an obstruction to the'en trance ofthe pin yet the resilient action of the flattened side lO allows it toyield-and This action of placing when located the resiliency of theside10 and the friction of the indentation serve to,

retain'it firmly and against the, possibility ofdisplacement and loss.'1, his obvious that'other modified details within, the scope of theclaim may "be adopted without departing from the essential featuresabove described.

What I. claim, as new and desire to secure by Letters Patent is: I

The combination with a pin of a. safety device comprising a tubularmember having one side externally flattened andireduced su said Sidebeing provided with a transverse indentation formingltm interiorprojection to frictionally engage the pinwhen the-point of the latter isinserted into the tubular member'.-

In testimony whereof, I afiix mysignature in presence of two witnesses.
